Founded in 1999 by Elina Vila and Agnes Blanch, Minim is an interior design studio focused on "maximizing the potential of each space, keeping all those original elements that have historical or contextual value," according to the partners. "The contrast between new and old is the best way to enhance the values of each period." In this classically detailed Barcelona flat, the designers used midcentury modern pieces by Hans Wegner, Arnie Jacobsen, and Poul Henningsen as a foil for the original stained glass windows and patterned cement tile floors. Go to Minim to see more of the firm's work and to tour the Minim Furniture Showroom.
